Young Pied Wagtail?

On the same night I took the pictures of the Hobby in the previous post, I also took these rather dark and grainy pictures in the ploughed field next to Rindle Wood.  As someone on the Manchester Birding Forum has asked for ID of a bird similar to this, I wondered if this was the bird they saw.  I just thought it was a young Pied Wagtail - what do you think?  Please leave your answers in the comments at the bottom of this post.
